Please check the following regarding tracking phenomenon.

​

The tracking phenomenon occurs when dust that accumulates in the gap between an outlet and a plug, or in a ventilation fan motor, absorbs moisture in the air, causing a current leak and resulting in a fire.

​

Tracking phenomenon can cause serious fires, so regular cleaning is necessary.

​

《Cleaning Procedures》

1. Unplug the power cord from the outlet and remove any dust with a dry cloth.

​

2. Turn off the ventilation fan, remove the cover, and remove any dust with a dry cloth.

​

〈Places where tracking is likely to occur〉

・Outlets located behind refrigerators, televisions, washing machines, etc., in places where dust tends to accumulate.

​

・Outlets and ventilation fans in humid places such as kitchens, washrooms, changing rooms, and toilets.

​

・An outlet used in a place where there is moisture, such as a humidifier.
